Hello
We contacted Mach Support and got this answer
High acceleration values make CV blending hold closer to the paths, thus LESS smoothing. He should NOT run the CV wizard unless he is using extreme angles. Set the look ahead to 200 or so.
Also, smoothing the points is not the job of Mach or any CNC. The job of the CNC is to follow the points as closely as possible!!
CV was designed to allow for faster roughing where each segment doesn't come to a complete stop. So CV does have the effect of smoothing. Within the constraints of the motors' capabilities. But it isn't going to smooth out very course polygons.
If he wants smoother polygons, the CAM program needs to make them more granular. That is the best bet for him.
If you are facing further problems related to Mach please contact their support.
It is better to use a licensed Mach4. We have Mach licenses available on our website for purchase. Please scroll to the bottom for prices.
